Please could you pop your software version in your profile under DCC ?
Ok...
1. You don't have the Plain Effector connected with the cloner. Presumably it wasn't selected when you added it. Solve that by dragging it into the effectors tab in the Cloner.
2. You don't need rotation on all directions - just P I think (if cam will be top view based)
3. Your quantize step value in the Field was not 4 as it should be.
Sort those out and works like a charm...
